HORSESHOE-CALK.

Specification of Letters Patent.

Patented June 13, 19116.

Application 'led March 5, 1915. Serial No. 12,322.

T0 all whom t may concern Be it known that we, ROBERT A. KELLER and CLINTON F. ROTH, citizens of the United States, residing at Catasauqua, in the county of Lehigh and State of Pennsylvania, and Allentown, county of Lehigh, and State of Pennsylvania, respectively, have. invented new and useful Improvements in Horseshoe- Calks, of which the following is a specification.

The present invention contemplates the provision of calks carried by an attaching plate capable of being readily attached to or removed from the shoe of the animal when desired, especially during sleety weather, the calks being designed to prevent the animal from slipping.

Among other features the invention embodies simplicity in construction, cheapness in manufacture, durability and efficiency in use.

The invention is fully set forth in detail in the following description, shown in the drawing wherein like numerals of reference indicate similar parts in the several views and in which Figure 1 is a bottom plan view of the shoe with the calks associated therewith. Fig. 2 is a longitudinal sectional viewtaken on line a-a of Fig. 1. Fig. 3 is a sectional view taken on line -b of Fig. 1. Fig. 4 is a detail view of the toe calli and attaching plate.

Upon reference to the drawing in detail 5 designates the body of the horse shoe, the latter being of usual construction.

The toe and heel calks 6 and 7 respectively, forming the subject matter of our invention, may be constructed from any suitable material preferably forged steel. The former consists of an attaching plate 8 of substantially rectangular formation in cross section, curved longitudinally to convform to the curvature of the shoe, and pro` these parts when in use, the plate being additionally secured to the shoe by means of the fastening element 10. Projecting centrally from the inner edge of the plate 8 is a tongue 11 adapted to be bent upwardly into a correspondingly shaped recess 12 in the inner edge of theshoe, to further assist in obviating turning or twisting of the plate thereon, and to relieve the fastening element 10 and projections 9 of undue strain. The call( proper indicated at 13 is substantially half-moon shaped, and coeXtensive in length with the plate 8, whereby the calk obtains an effective purchase upon the surface and prevents slipping of the animal. By reason of the specific formation of the calk 13, the latter will wear in such manner so as to always retain a sharp edge.

Both of the heel calks are similarly constructed, and consist of a plate 14 of greater width than the width of the heel, the projecting portions 15 being adapted to be bent into engagement with the opposite edges of the shoe, to retain the same thereon, the plates being additionally secured to the shoe by means of the fastening element 16. One of the projecting portions 15 is arranged in a correspondingly shaped recess 17 formed in the inner edge of the shoe to prevent turning or twisting ofy the plate thereon. The heel calli proper indicated at 18 is substantially L-shaped, to obtain'an effective purchase with the surface, to prevent slipping of the animal, and possesses the same advantages with respect to its wear as that described -in connection with the toe calli. Manifestly by reason of the construction hereinabove described either the toe or heel calks, or both may be readily associated with or detached from the shoe when desired, and when associated therewith will be held fixed relatively to the shoe.

It is believed that from the foregoing description the nature and advantages of the invention will be readily apparent withoutV requiring a more extended explanation and therefore the same has been. omitted.l i

What is claimed is As a new article of manufacture, a horse shoe calk comprising an elongated plate of a width greater than that of the shoe, means for fastening said plate to one side of the shoe, whereby said projecting portions of the plate are adapted to be set up into en- In testimony whereof We aliX our signugagement With the opposite edges of the tures in presence of two Witnesses. shoe, and a substantially L-slmped strip of ROBERT A.
